Assumptions

This is an estimate. Use conservative inputs and validate with actual invoice and collections data.
DSO cash release is estimated only on the in-scope portion of revenue you expect to impact.
Dispute and short-pay recovery depends on evidence quality, customer behavior, and internal follow through.
Payback assumes savings convert to cash release and the operating cadence is sustained.

Enter annual invoiced revenue, current DSO, and target DSO.
Set in-scope revenue percent to reflect what the new controls can realistically impact.
Add annual dispute and short-pay dollars and a conservative recovery percent.
Generate results, then copy or download the memo and export a one-row CSV for Finance.

DSO cash release: estimated cash freed by reducing days outstanding on the in-scope portion of revenue.
Dispute and short-pay recovery: recovered dollars from resolving disputes faster and preventing recurring short pays.
Total cash impact: combined cash acceleration estimate (DSO cash release plus recovery).
Payback: one-time implementation cost divided by estimated monthly cash release (if implementation cost is provided).

Overstating scope: keep in-scope revenue percent conservative unless you have enforcement and ownership.
Confusing revenue and AR: use annual invoiced revenue, not bookings or contract value.
Assuming collection without process: dispute recovery requires intake, evidence, owners, and cadence.
Treating payback as guaranteed: payback assumes the operating rhythm is sustained.
